The mechanical behavior effect of FDM process by using PA6 and PA66 for varying its infill density on a rectilinear pattern

Abstract

Fusion deposition modeling (FDM)is an additive manufacturing technique that allows for the cost-effective, quick, and simple creation of high strength specimens with accurate dimensions. The major goal of our proposed research is to compare the mechanical properties of polyamide 6 (PA6) and polyamide 66 (PA66) in a rectilinear structure fabricatedby using FDM technique. The specimens are produced with different infill percentages for rectilinear structures such as 50%, 75%, and 100% respectively. These materials are used for testing, such as tensile strength, yield strength, percentage of elongation, clashed with the exploratory results. In the FDM process, the major influencing process effect of infill percentage reveals that rectilinear structures with 100% infill produce greater strength than rectilinear structures with 50% and 75% infill for both materials. In the future, it will be useful for engineering applications in the development of diverse parts.
